Design chart nomograph for RIGID PAVEMENT

Concrete Elastic Modulus, $E_c({10}^6)$

Example:

$k=72$pci

$E_c=5{10}^6$

$S_c^{\text{'}}=650$

$J=3\mathrm{.}2$

$C_d=1\mathrm{.}0$

Solution: $D=10\mathrm{.}0$ inches $($nearest halitinch, from segment $2)$

Zr$=-1\mathrm{.}645,$ reliability with R $=95\%$

initial Psi: $4\mathrm{.}5,$ at TSi$=2\mathrm{.}5$
